Two balls collide on a pool table. Before the collision, ball 1 is traveling with a speed of 4 m/s, and ball 2 is at rest. After the collision both balls are in motion.
What has happened in this collision?

A. There was no change in ball 2's velocity, therefore momentum was not conserved.

B. Ball 2's velocity decreased, and it gained some of ball 1's momentum.

C. Ball 1's velocity decreased, and it gained momentum.

D. Ball 2's velocity increased, and it gained some of ball 1's momentum.

Answers

Answer 1

Answer:

D

Explanation:

With the collision, obviously Ball 2's velocity increased, while Ball 1 slowed down a little bit due to the impact. This decrease in velocity caused a decrease in Ball 1's Momentum. Satisfying both conditions, option D is right.

Answers

Answer:

a. Indivisible.

b. Mass.

c. Masses.

d. Compound.

e. Elements.

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such defines the structure of a chemical element.

Generally, these atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

Hence, all the physical properties of a mineral result from the mineral's internal arrangement of atoms.

The following are statements postulated by the Dalton's atomic model;

a) Elements are composed of minute, indivisible particles called atoms.

b) Atoms of the same element are alike in mass and size.

c) Atoms of different elements have different masses and sizes.

Determine the pH, pOH, [H+], and [OH−] of a solution in which 0.300 g of aluminum hydroxide is dissolved in 184 mL of solution.

Answers

Answer:

[OH⁻] = 0.0627M

pOH = 1.20

pH = 12.8

[H⁺] = 1.59x10⁻¹³M

Explanation:

To solve this question we must, as first, find the molarity of Al(OH)₃ in the solution -Molar mass Al(OH)₃: 78.00g/mol-:

0.300g * (1mol/ 78.00g) = 3.846x10⁻³ moles

In 184mL = 0.184L:

3.846x10⁻³ moles / 0.184L = 0.0209M Al(OH)₃. Three times this molarity = [OH⁻]:

[OH⁻] = 0.0209M * 3

[OH⁻] = 0.0627M

pOH = -log [OH⁻] =

pOH = 1.20

pH = 14 - pOH

pH = 12.8

And [H⁺] = 10^-pH

[H⁺] = 1.59x10⁻¹³M

Decomposition of potassium chlorate are performed in the lab to make oxygen. You are strictly advised to be careful with it. Why is that, what might happen?​

Answers

Potassium chlorate itself has a lot of toxicity and are bad for the skin and lungs. The reason why potassium chlorate needs to be handled with care is because while the thermal decomposition takes place, potassium chlorate starts to emit toxic fumes of chlorine and potassium oxide and it also emits very toxic fumes of hydrogen chloride and K2O.

A certain type of material allows electricity to flow through it, but it does not flow quickly or easily through it. Is the material a good or poor conductor? Does it have a low or high resistance?

Answers

A substance through which an electrical current flows poorly would be said to be a poor conductor. That is, the substance has a low conductance (or conductivity). There’s a nuance between the two terms, but it shouldn’t matter for our purposes.

Since such a material resists the flow of electric charge, the material can be said to have a high resistance (or high resistivity).

Mathematically, resistance and conductance are reciprocals of one another; a low conductance implies a high resistance, and a high conductance implies a low resistance.

Answer:

if you will decrease the HCO3- so the less H+ ion will be form and reaction will more likely shift to product and when HCO3- decreases pH value increases and vica versa for the increasing HCO3 the more H+ ion will be form and reaction will shift to product and the pH value will decreases!!

I've doubt in reaction shift coz whatever is the amount of HCO3- this is completely gonna form number of H+ so reaction shift may or may not be same!!

H2SO4 + 2NaOH → Na2SO4 + 2H2O what volume of water vapor will be produced if you start with 71.5 g of sulfuric acid and excess of sodium hydroxide

Answers

Answer:

Explanation:

Find the molar mass of H2SO4

2H = 2 * 1 = 2

S  = 1 * 32 =32

O4 = 4*16 = 64

total             98

Find the number of mols in 71.5 grams

mols = given mass / molar mass.

given mass = 71.5

molar mass = 98

mols = 71.5/98

mols = 0.7296 mols of H2SO4

Find the moles of H2O

From the Balanced equation, every mol of H2SO4 produces 2 moles of H2O

mols water = 2 * 0.7296

mols water = 1.4592

That's as far as I can take you. I have to know a great deal more to get the volume of H2O

How many militias of 5.0 M H2SO4 (aq) stock silly toon are needed to prepare 100. Ml of 0.25 M H2SO4 (aq)

Answers

Answer:

5 mL

Explanation:

As this is a problem regarding dilutions, we can solve it using the following formula:

C₁V₁=C₂V₂

Where subscript 1 refers to the initial concentration and volume, while 2 refers to the final C and V. Meaning that in this case:

C₁ = 5.0 MV₁ = ?C₂ = 0.25 MV₂ = 100 mL

We input the data:

5.0 M * V₁ = 0.25 M * 100 mL

And solve for V₁:

V₁ = 5 mL

Answer:

5 mL of 5.0 M H₂SO₄ (aq) are needed to prepare 100 mL of 0.25 M H₂SO₄ (aq).

Explanation:

In chemistry, dilution is the reduction of the concentration of a chemical in a solution.

Then, dilution consists of preparing a less concentrated solution from a more concentrated one, and it consists simply by adding more solvent to the same amount of solute. That is, the amount or mass of the solute is not changed, but the volume of the solvent varies: as more solvent is added, the concentration of the solute decreases, since the volume (and weight) of the solution increases.

A dilution is calculated by the expression:

Ci*Vi = Cf*Vf

where:

Ci: initial concentration Vi: initial volume Cf: final concentration Vf: final volume

In this case, you know:

Ci=5 MVi= ?Cf= 0.25 MVf= 100 mL

Replacing:

5 M*Vi = 0.25 M* 100 mL

Solving:

[tex]Vi= \frac{0.25 M*100 mL}{5 M}[/tex]

Vi= 5 mL

5 mL of 5.0 M H₂SO₄ (aq) are needed to prepare 100 mL of 0.25 M H₂SO₄ (aq).
